The Application of a Novel Endoluminal Robotic System for Colorectal Endoscopic Submucosal Dissection

Plain-language summary
Endoluminal surgery through natural orifices is an effective, "incisionless" treatment for benign lesions and early-stage cancers in the urinary tract and gastrointestinal (GI) tract. However, current practice suffers from the use of basic surgical instruments that lack dexterity and the ability to perform effective tissue retraction and provide triangulation. This is illustrated in endoscopic submucosal dissection (ESD) of GI tumors, which is a highly effective technique that has limited widespread adoption due to the exceptionally steep learning curve created by unintuitive and cumbersome instruments. It is suggested that a robotic system may improve en bloc resection capabilities in the GI tract by providing surgeons with dexterous and precise bimanual instrument control. This study aims to evaluate the clinical feasibility and safety of colorectal ESD using a novel endoluminal robotic system - the Intilume System by Agilis Robotics. It is a prospective, single center study consistent with a Stage 1 (Innovation) study described in the Innovation, Development, Exploration, Assessment, Long-term Study (IDEAL) framework. The primary study endpoints are en bloc resection rate and perioperative complications. The secondary study endpoints include R0 resection rate, dissection related metrics, conversion rate, and post-procedure recovery. This study will provide information on the feasibility and safety of the Intilume System developed by Agilis Robotics in performing colorectal ESD. This study may provide pertinent evidence for the continued development of this robotic technology.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Patients diagnosed with nonpedunculated early rectal neoplasms \>/= 2 cm in size in the rectum (\>/= 3 cm and \</= 18 cm from the anal verge) that are deemed not feasible for en bloc resection with conventional polypectomy or endoscopic mucosal resection (EMR) as judged by two experienced endoscopists
* American Society of Anesthesiologists (ASA) grading I-III
* Informed consent available
Exclusion Criteria:
* Presence of endoscopic signs of massive submucosal invasion (including excavated/depressed morphology, Kudo's pit pattern Type V, or Sano's capillary pattern Type IIIB)
* Evidence of deep invasion on endorectal ultrasonography
* Unfavorable histopathologic features on biopsy (mucinous cancer, poor differentiation, or gross submucosal invasion)
* Patients with other synchronous colorectal neoplasms in addition to the index neoplasm that are indicated for surgical resection
* Patients with recurrence from previous EMR or ESD
* Patients with non-correctable coagulopathy
* Patients with contraindications to general anesthesia
* Vulnerable population (e.g., mentally disabled, pregnancy.)
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
